flutter/engine#44248 seems to have improved the average rasterizer time for the backdrop filter benchmark, but potentially raised the floor on the gallery 90th percentile test (albeit the attribution is tenuous). Can we double check the implementation to make sure there isn't something we missed that might negatively effect the 90th percentile

backdrop filter average raster time benchmark drop

gallery 90th percentile increase

(notice that the floor never reaches 10ms around the time that PR landed)
